Well, if you want to watch it, then use here it has all of the episodes.
Yeah, BT3 is pretty good, I got Raging Blast in December, and it's really disappointing because they took out a heck of a load of characters that were in BT3, so yeah, that sucks. But there are some good things about it, like they added SSJ3 Vegeta and Broly, and the graphics are awesome.
